Right-click your device → Properties → Port Settings → Advanced → Change COM Port Number to COM 3 or COM 5 (ECM Titanium does not recognize COM ports above 8). | | "Runtime error 429: ActiveX component can't create object" | Run CMD as admin: regsvr32 C:\ECM_Titanium\System\mscomctl.ocx | | The software opens and instantly closes | Disable Windows Defender Real-time Protection temporarily, or add C:\ECM_Titanium as an exclusion in Virus & Threat Protection settings. |
